The “Infrastructure Backbone” Behind the Gongming Reservoir–Qinglinjing Reservoir Interconnection Project

GLUS Supports Shenzhen’s Major Water Conservancy Project with Professional Rebar Connection Solutions

Behind the rapid development of Shenzhen, a major water conservancy project crucial to urban water security is progressing steadily — the Gongming Reservoir–Qinglinjing Reservoir Interconnection Project (hereinafter referred to as the “Gongqing Project”).

As the largest single-investment water conservancy project since Shenzhen’s establishment, the Gongqing Project not only undertakes the important task of ensuring water supply security for Shenzhen’s central districts, but also shoulders the strategic responsibility of providing emergency water supply support for Hong Kong.
In such a high-standard, high-difficulty, and high-requirement project, the quality of rebar connections directly affects structural safety. GLUS is providing solid support for this major project through its professional products and service capabilities.

I. Behind This Mega Project Lies a Strategic Water Security Layout

Project Name: Gongqing Project Civil Works Section III

Project Location: Shenzhen

Project Time: November 2025

As an important part of Shenzhen’s backbone water network, the Gongqing Project consists of:

• 1 water transmission trunk line of 41.28 km

• 2 water intake structures

• 3 maintenance access tunnels

• 4 pumping stations

• 5 branch distribution lines

• 18 shafts

Together, these form a critical part of Shenzhen’s “three vertical and four horizontal” backbone water network.

The project has a total water transmission capacity of 2.67 million cubic meters per day, with a total estimated investment of RMB 10.9 billion. Upon completion, the project will enable joint allocation of water resources from the Dongjiang and Xijiang Rivers, effectively ensuring water supply security for central Shenzhen and meeting Hong Kong’s emergency water supply needs.

This is not only an upgrade of urban water supply capacity, but also a forward-looking strategic deployment of water resources.

II. Extremely Difficult Construction Conditions Demand “Millimeter-Level” Precision in Rebar Connections

Major projects always come with major challenges, and the construction environment of the Gongqing Project is far more complex than that of ordinary projects:

18 Ultra-Deep Shafts

The shaft structures require extremely high precision in rebar cage connections, where any deviation may affect the stability of the entire structure.

Cutoff Walls Over 100 Meters Deep

The reinforcement cage for the cutoff wall in the Shenxianling section alone weighs 105 tons, placing extremely high demands on the strength and stability of rebar connections.

Complex Karst Geology

Abundant groundwater and unstable rock layers make traditional rebar connection methods difficult to apply effectively.

Under such complex working conditions, rebar connections must satisfy not only strength requirements but also offer:

✅ High stability
✅ High adaptability
✅ High construction efficiency

This is exactly where GLUS demonstrates its value.

III. Centered on Rebar Couplers, GLUS Provides an Integrated Connection Assurance Solution

To meet the project’s complex construction demands, GLUS has provided reliable rebar connection assurance centered on rebar coupler products.

Relying on its mature production system and technical service capabilities, GLUS supports the project from three aspects:

1. High-Quality Products Ensure Reliable Connections

Rebar connections are critical nodes in structural safety.
Through strict product quality control, GLUS ensures that every coupler meets the standards required for major projects, providing reliable support for rebar connections under complex conditions.

In key structures such as ultra-deep shafts and cutoff walls, high-quality rebar couplers effectively guarantee:

• Stable joint strength

• Reliable connection precision

• Strong adaptability to construction conditions

This makes complex structural construction safer and more efficient.

2. Rapid Supply Ensures Continuous Project Progress

Major projects proceed at a fast pace, requiring rapid material supply response.

To ensure continuous progress, GLUS relies on its production base layout to provide:

• Rapid production response

• Accurate batch supply

• Efficient logistics support

This ensures that rebar connection materials arrive on time, preventing supply issues from affecting construction milestones and allowing product performance to be fully realized on-site.

3. On-Site Technical Support Solves Construction Challenges

In addition to products, technical support on the construction site is equally important.

GLUS provides professional on-site technical support to promptly resolve connection issues during construction and provide technical assistance for critical structural work, including:

• On-site connection guidance

• Rapid response to construction issues

• Support for complex application scenarios

Through the dual guarantee of “products + technical service,” construction efficiency and connection quality are improved simultaneously.

IV. Shared Values Are the Foundation of Efficient Collaboration

Successful cooperation depends not only on product compatibility, but also on aligned values.

The construction contractor adheres to the principle of:

“Building water conservancy projects that last for a century”

Strictly controlling every process to ensure project quality.

For 23 years, GLUS has remained committed to:

“Ensuring safety for construction”

From raw material selection to manufacturing process refinement, GLUS always adheres to high standards.

Both parties share strong consensus in the following areas:

Safety First

The contractor pursues “zero accidents and high quality,” while GLUS ensures product quality through strict factory inspection standards.

Efficiency

The contractor emphasizes efficient project progress, while GLUS’s rapid response service ensures uninterrupted supply.

Quality Assurance

Both parties share the goal of building high-quality projects that stand the test of time.

This high degree of alignment has enabled an efficient collaboration model, achieving:

✅ Qualified products
✅ Controllable progress
✅ Excellent quality

V. Behind This Hard-Core Project Are Hard-Core Products and Services

As a major livelihood project in Shenzhen, the Gongqing Project requires not only strong construction capability but also reliable material supply and professional service support.

Through:

• High-quality rebar connection products

• Rapid-response supply system

• Professional on-site technical support

GLUS has provided strong assurance for the project’s complex structural construction and contributed professional strength to the development of major water conservancy infrastructure.

Conclusion: Supporting Major Projects Through Professional Connections

From urban water security to major infrastructure support, although rebar connection is only one part of construction, it directly affects the safety and stability of the entire structure.

In major national-level projects such as the Gongming Reservoir–Qinglinjing Reservoir Interconnection Project, GLUS demonstrates the responsibility and commitment of a professional rebar connection enterprise through its reliable products and full-process services.

In the future, GLUS will continue to support more key projects with dependable products and professional services, contributing to the high-quality development of infrastructure construction in China.
